in patients without accompanying symptoms, 42.8% in patients accompanying with body weight loss, 66.7% in patients accompanying with anemia, 33.3% in patients accompanying with diarrhea. Conclusion: The indications for capsule endoscopy in the study of chronic abdominal pain should be more precisely defined to achieve a greater clinical efficiency in this disorder. The accompanying symptoms especially anemia and body weight loss should be regarded as a valid indication for capsule endoscopy. Key Word(s): 1.

Because it is difficult to perform en bloc resection with conventional endoscopic mucosal resection, there are some limitations, for example, histopathologic this website misdiagnosis and risk of local recurrence. The purpose of this study is to evaluate efficacy and comparison of two advanced endoscopic resection techniques, endoscopic mucosal resection with circumferential incision (EMR-CI) and endoscopic submucosal dissection (ESD). Methods: From February 2009 to May 2012, we enrolled 71 patient who underwent EMR-CI or ESD to remove laterally spreading tumor (M : F = 45 : 26, age: 61.8 ± 7.9). To anaysis clinical outcomes of resection techniques, we reviewed several indicator retrospectively such as en bloc resection rate, complete resection rate, perforation rate, local recurrence rate. Results: The average size of laterally spreading tumor was 2.3 ± 0.96 cm (range: 1 cm – 7 cm). A large percentage of them was located in rectum (26 cases) and ascending colon (21 cases). Macroscopically, granular homogeneous type (22

cases) and granular mixed nodular type (23 cases) were common. On histopathologic examination, 36 lesions were low grade dysplasia, 18 lesions were high grade dysplasia and 15 lesions were adenocarcinoma. Compare with another types of laterally spreading tumor, mixed nodular 上海皓元 type showed higher incidence of adenocarcinoma. By the tumor size, en bloc resection rates were as in the followings. In cases of tumor size under 2 cm, both EMR-CI (17/17) and ESD (7/7) were 100%. In cases of size 2 cm to 3 cm, EMR-CI was 70% (22/31), ESD was 88% (8/9). Size exceed 3 cm, EMR-CI was 50% (2/4), ESD was 80% (4/5). Conclusion: The overall en bloc resection rate of EMR-CI (78%, 41/52) and ESD (89%, 17/19) were higher than that of conventional endoscopic mucosal resection. The en bloc resection rates were not statistically different between the two resection techniques (P = 0.305).
